A continuous press with a steam-injection device from both sides of the press was designed and set up. The capacity of the press is 100 tons, the hot pressing part is 1,550 mm long and 500 mm wide with tapered entrance of 1,150 mm length, and two steel belts of 0.8 mm thickness were used for feeding a mat.The width and thickness of the products were 300 mm and 100 mm. Temperature of super-heated steam injected from the both sides of the mat was 160 ^ﾟC and that of hot-platens was 170 ^ﾟC. The maximum feeding rate was 3 m/min. The rationality of the structure and operation method of this newly developed press was discussed and the adaptability of this press to the production of continuous materials using different raw materials was discussed on experimental results.Raw materials used were lauan semi-flake type particles, 2.0 mm thick veneers of Japanese cedar and mesh-like sheets materials which are produced by crushing the above veneers with a roller press and called "Wood-Zephyr".Continuous materials of 100 mm thickness and 300 mm width were produced by this press and temperature distribution in the mat during pressing and the properties of the products were measured. The results are as follows :1) Temperature distribution was very even when particles are used singly or in layer-structure alternating with Wood-Zephyrs, while it varies much when veneers or Zephyrs were used alone.2) In the former case, temperature reaches more than 100^ﾟC soon after the mat section enters into the steam-injecting part.3) Particle products and particle/Zephyr composite products had homogeneous properties and the latter had enough bending properties for structural use.

设计并建立了一台两侧注汽的连续压机。该压机的生产能力为100吨，热压部分长1,550 mm，宽500 mm，锥形入口长1,150 mm，产品的宽度和厚度分别为300 mm和100 mm，从板坯两侧注入的过热蒸汽温度为160 ℃，热压板的温度为170 ℃。最大进料速度为3 m/min.根据实验结果，讨论了新研制的压榨机结构和操作方法的合理性，并讨论了该压榨机对不同原料连续物料生产的适应性. 2.0 mm厚的日本雪松单板和网状片材，其通过用辊压机破碎上述单板而生产，并被称为“Wood-Zephyr”。通过该压制机生产100 mm厚和300 mm宽的连续材料，并测量压制期间垫中的温度分布和产品的性能。结果表明：1）颗粒单独使用或与木-西风交替使用时，温度分布非常均匀，而单板或西风单独使用时，温度分布变化较大; 2）颗粒单独使用时，板坯段进入注汽部分后，温度很快就达到100 ℃以上; 3）颗粒制品和颗粒/西风复合制品性能均匀，后者具有足够的弯曲性能，可用于结构使用。
